The schematic of the phone audio interface I built: I have added a switch to choose between a 620 ohms and 33k resistor. This attenuates the signal coming out from the interface, provided there is at least a small load (10k works fine) …
Simple Telephone Amplifier Circuit - Making Easy Circuits
https://makingcircuits.com/blog/simple-telephone-amplifier-circuit/
This telephone pickup coil, when placed close to the telephone, picks up. (by mutual induction) the audio frequency variations of currents produced by the telephone microphone. These signals through the coupling, are fed to the IC amplifier for amplification.

This is an easy telephone amplifier circuit. It will increase the signal of the telephone lines up. Then, drive the relay to controls the large electric bells that louder than a general phone. This circuit is modified from the speaker protection circuit, so easy and cheap. How it works. Figure 1 the circuit diagram.

Typically the telephone central provide from 200 to 400 ohms of series resistance to protect from short circuits and decouple the audio signals. Typical telephone line bandwidth is around 180-3200 Hz, which was what phone companies decided years ago be sufficient for speech intelligibility while allowing them to multiplex many calls over coax and twisted pair.

You will have a wide variety of telephone jacks to choose from but the wiring for a single line phone service will be standard. Keep in mind that the colors of the telephone wiring in your home will be typically one of two types or insulation colors. Older telephone wiring was a basic Cat-3, 4 conductor or 2-pairs with red, green, black, yellow.

Analog Telephone Overview An analog telephone line, at its simplest, is nothing more than a 600-ohm balanced line. One pair of wires carries duplex (see Note 1 directly below) audio and 48 VDC for telephone operation. The 48 VDC is current limited by series resistors (one in each leg), therefore phones “on-hook” (no current drawn) typically measure 48 VDC, while …
